摘要

我们报道了Ho: YAG激光束(波长λ ~ 2.1 μm)在近红外、中红外和远红外区域的频率转换实验结果，旨在扩大紧凑多光谱相干辐射源的光谱组成。实验发现，在连续波和重复脉冲条件下，激光到二次谐波的转换效率分别达到32%和54%。中红外波段(λ = 3.5 ~ 5.0 μm)的参数转换效率为55%，远红外波段(λ = 8 ~ 8.2 μm)的参数转换效率为10.5%。

Nonlinear frequency conversion of a Ho :YAG laser beam

We report the results of experiments on frequency conversion of a Ho : YAG laser beam (wavelength λ ∼ 2.1 μm) into the near-, mid-, and far-IR regions, aimed at expanding the spectral composition of compact multispectral sources of coherent radiation. The experimentally found laser conversion efficiency into the second harmonic reaches 32 % and 54 % in the cw and repetitively pulsed regimes, respectively. The parametric conversion efficiency into the mid-IR range (λ = 3.5 – 5.0 μm) reaches 55 %, while for the far-IR range (λ = 8 – 8.2 μm) it turns out to be 10.5 %.
